Raidho TD4.8

This is truly aunique and revolutionary drive unit! 100% developed and built in-house by Raidho. The goals was simple: nocoloration and outstanding dynamic capabilities.

The motor comprisesof a very strong magnet (N52Neodymium) with an unseen even magnet field, coupledwith an underhungtitanium voice coil. This arrangementgives the drive unitthe most powerful underhung magnetsystem in the world. The benetfit from an underhung voiciecoil over the traditional overhung, is that it is much more linear and better dynamic capabilities. The result is perfect transient response with no measurable distortion.

To enhance the strength of the magnetic motor even further, we designed a new titanium voice coil using square shaped wire that eleminiates air in the voice coil windings. Leaving no possibility for air gaps to interfere with the magnetic field. The complete magnet system, as well as the basket itself is shaped like a turbine which eliminate any sound reflections, which would otherwisesmear the original sound. The solid coppering over the inner pole piece very effectively minimizes inductance and linearizes impedance. The suspension parts are as soft as possible to insure as little mechanic restraints to movement of the diaphragm.
